i3 4To alll whomfit muy concern Beit known that I, JAMES COLMAN BOWEN,

.V il of North Springfield, 'in 'the county of Windsor and State ot' Vermont,- have invented a.

5 new and useful vImproveii'ient in l'eirigerators,

@of which the following is a specifica-tion. V Refrigerators have been used to supply air i to cars made air-tight and surrounded with lion-conducting material; but I have found lxo that this is not s'iiiiicient rthat it is necessary V to provide for forcing the air several times p around through the articles Sin the car, and with the air already iii the. car back and through the ice-box, so as to bring all the lair and articlesin the car to aunit'ornily cold temperature. This I acconiplishby allowing the cold air from tliebottom of ice-box to 'fall .directly to the bottom of ca r aiidforce the warm air through the top of car, and in at .izotlie top ot' ice-box', whence. it passes over the ice'. After passing several times around through car and ice-boit all the air becomes alike cold, and the temperature in the car will not be so'rcadiLiv lowered afterward below the point desired'.

In the accompanying drawings, Figure 1 is a Vlongitudinal vertical section, representing a railway-car in connection or `con-iniunication with 'a rcl'rigerating apparatus for the purpose of cooling its interior and contents. Fig. 2 is a longitudinal horizontal section ofthe car.'

Similar letters ot' reference indicate corresponding parts. i

A represents a railway-ear, 'which may be of any construction which will lender it suitable for the transportation of provisions or fruits. Near one Yend of the car is avertical partition, B, extending. transversely from side to'side and from the to'p of the car nearly to the bottom, so as to forni a vertical tine, U,

with an opening, d, at the bottom thereof,

leading to the interior of the. can The top of this tluc C is provided with a gate or cutoff, `E, :for the .purpose of closiiigjt. whendesired. In thc top of thc car, at any' suitable point, is' an' opening, f, provided withv'a gate or cutoff,

` 'Gfwhich may be closedwifheii desired.

chamber, and the lower end extends considerably below the exterior `of said bott/0m, in order to communicate with the fine C, asherenafter described. At the end of the chamber H farthest from the pipe J, and near the top ot' said chamber, is an opening, i, which communicates with avertical pipe, K, the lower end of which extends considerably below the bottom ofthe chamber, for communication with the openingf iii the-top ofthe c ar.

The pipe J is pro-vided with a valve, L, which may be closed so as to cnt oft` communication with the exterior of said pipe, and the openingi is provided with a gate, M, tor a similar purpose.' Tliclower ends of the pipes J and K are provided with-telescopic sliding tubes P P2, to' accommodate them to cars or other receptacles of' ditiereut heights.

The car or receptacle A, having received the contents which-arc to be transported therein,

opening f. The valves or ciit-o's L, E, G, land Mare then opened, so as to allow communication between the chai-uber and car A. The cold air passes down the pipe and flue C into the car A, and the warnier air escapes from the car through the opening f and passes u p through the pipe K and into the ice-chamber H,.as indicated .by the arrows in Fig. V]. Then the air iiithe car has been siitiicienltly cooled the valves or cut-otfsare closed and the car is disconnected from the ice-chamber and placed in position for transportation. v

I am aware that it is not broadly new to furnish air-tight cars witlivcold air from a istil,- tio-nary refrigerator before they are started for their destination with meats, fruits, or other products; but

. A stationary refrigerator for supplying cars with cold air, consistiiigot' the ice-box H,ha,v ing the valved opening near the top, the pipe li to connect it with tlic top of car, and ,the

valved pipe J to connect with a. pipe or flue leading to the bottom oi' car, whereby, when above the car, the air can bc circulated severa-l times through the car, mi described. f
